Apr 2026

Summary

A short technical screen at Weride for a frontend role, basically just a 5-minute conversation about how you use AI tools in your actual work. Pretty low-pressure but they wanted specifics, not vague hand-waving.

Questions Asked (1)

How do you understand AI tools like LLMs, ML models, and agents, and how do you actually use them in your day-to-day engineering work? Give concrete examples across things like coding assistance, code review, design exploration, and debugging, and also talk about where you think they fall short or where you deliberately avoid relying on them.

Author's notes

This is the kind of question that sounds easy until you're actually on the spot and realize your examples are kind of shallow.

Suggested Approach

Structure your answer around a clear mental model of AI tools (LLMs, ML models, agents) and then walk through concrete frontend engineering examples for coding, review, design, and debugging. Be honest about limitations and show deliberate judgment about when to avoid AI, emphasizing verification and critical thinking.

Pro tip: Frame AI as an 'accelerator, not an oracle'—always verify outputs, especially for security, performance, and accessibility concerns. Mention that you keep a personal log of AI wins and failures to continuously refine when to trust it.

1. Define your mental model

Briefly explain how you understand LLMs (probabilistic text generators), ML models (pattern recognizers for specific tasks), and agents (autonomous tool-users). Emphasize their strengths and inherent limitations.

2. Coding assistance examples

Give 1-2 concrete examples where AI helped you write boilerplate, generate unit tests, or translate designs to code faster, and note how you verified correctness.

3. Code review and design exploration

Describe using AI to catch simple issues, suggest refactors, or brainstorm component APIs and state management patterns, while stressing that final decisions require human judgment.

4. Debugging and limitations

Share a debugging example where AI helped trace an error or suggest fixes, then discuss where it fell short (e.g., complex race conditions, browser-specific quirks) and why you avoided relying on it.

5. Deliberate avoidance and verification

Explain situations where you deliberately avoid AI (e.g., security-sensitive code, performance-critical algorithms, novel architecture) and how you verify AI outputs to maintain quality.

Key Points to Mention

LLMs as probabilistic assistants, not deterministic compilers—outputs need verification.
Concrete frontend examples: generating React components, writing Jest tests, suggesting CSS fixes.
Using AI for design exploration: brainstorming component props, state machines, or accessibility improvements.
Debugging: AI can suggest common fixes but struggles with context-specific bugs like memory leaks or cross-browser issues.
Limitations: hallucinations, outdated knowledge, lack of project context, and inability to run code.
Deliberate avoidance: security-sensitive code, performance-critical algorithms, and novel architecture decisions.
